Which word is used incorrectly in the following sentence? For whom was that email intended?

Correct Answer: B

Rationale: The word 'whom' should be used instead of 'who' in the sentence to make it grammatically correct. 'Who' is used as the subject of a sentence, while 'whom' is used as the object. Therefore, the correct form of the sentence should be: 'For whom was that email intended?' Choices A, C, and D are used correctly in the sentence and do not need any changes.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is needed at the end of the sentence to indicate the completion of the thought and to make it a grammatically correct statement. The other options (comma, question mark, exclamation mark) do not fit the context of the sentence. In this case, a period is used to end a declarative sentence, stating a fact without needing any additional punctuation for the context provided.

Correct Answer: C

Rationale: The correct spelling is 'embarrassing.' It is spelled with two consecutive r's and two consecutive s's. Option C is the only choice with the correct spelling. Options A, B, and D all have incorrect spellings. 'Embarrasing' (Option B) is missing an 'r,' and 'Emberassing' (Option D) has an extra 'e' and a missing 'r' and 's.' Therefore, the correct answer is Option C.

Correct Answer: B

Rationale: The correct answer is 'to roll.' In this sentence, 'started' is followed by the infinitive form of the verb 'to roll.' The construction 'started to roll' indicates the beginning of the action of the wheelchair moving down the corridor. Choice A ('roll') is incorrect as it lacks the infinitive marker 'to' needed after 'started.' Choice C ('rolled') is incorrect as it is the past tense form of the verb, not suitable for the sentence's context. Choice D ('will roll') is incorrect as it indicates a future action, not the past action indicated by 'started.'

Correct Answer: C

Rationale: The word 'datum' is singular, and the correct plural form of 'datum' is 'data.' Therefore, the sentence should use 'data' instead of 'datum' to be grammatically correct. In the sentence provided, 'datum' should be replaced with 'data' to maintain proper grammar and syntax. Choices A, B, and D are used correctly in the sentence, so they are not the correct answer.
